The government will readvertise for a new chair of the body that runs the National Citizen Service after failing to appoint a suitable candidate first time around.
The Department for Digital, Culture, Media and Sport began advertising for a chair for the National Citizen Service Trust in July last year.
The new chair is expected to take over when the trust converts from a community interest company to a royal charter body.
But a statement from the DCMS on Friday said that after carefully considering the applicants for the position, the Prime Minister, Theresa May, had chosen to re-run the competition.
The statement said a new campaign for the position would be launched in due course, "and will be focused towards identifying a candidate with appropriate commercial experience, or experience of setting direction and supporting an organisation to develop".
It said the government was committed to the continued development of the NCS programme.
"The new chair will lead NCS through a period of organisational change, so it is vital that we find the right candidate for the job," it said.
Stephen Greene, co-founder and chief executive of RockCorps, which provides tickets to concerts for young people who volunteer, was appointed chair of the NCS Independent Management Body, the forerunner to the NCS Trust, in November 2012.
He will to remain in post until the new chair joins, which is expected to be when the trust becomes a royal charter body.
The NCS offers 16 and 17 year-olds the chance to take part in projects including community work, physical challenges and residential placements.
The government passed legislation last year to enable the NCS Trust to transfer to a royal charter body, allow the government to provide grant-in-aid funding to the trust and require it to publish a business plan at the start of the year.
A report from the House of Commons Public Accounts Committee said last year that the high cost of the scheme could not be justified and its participation targets remained challenging despite being significantly reduced.
The government has committed £1.5bn to the scheme between 2011/12 and 2019/20.
